I'd like to edit mine a little bit:
I'll stay with my first (serious) choice in the post above, but I'd like to add a couple that would also make sense for me:
Pull Me Under -- Dream Theater
Hit the Floor -- Bullet for my Valentine
I Will Not Bow -- Breaking Benjamin
Another One Bites the Dust -- Queen (ha)
And as for tombstone inscription
"Someone finally wised up and blocked all the spawn points"
